-<p id="830726" class="block-content">
-In case you haven't already used it, <a href="http://prototype.conio.net">prototype.js</a> is a

-<p id="830727" class="block-content">
- If you tried to use this library recently, you probably noticed that documentation is not one
- of its strongest points. As many other developers before me, I got my head around prototype.js by
- reading the source code and experimenting with it. I thought it would be nice to take notes while
- I learned and share with everybody else.

-<h2 id="6604">Using the <tt>$()</tt> function</h2>
-<p id="830729" class="block-content">
- The <tt>$()</tt> function is a handy shortcut to the all-too-frequent <tt>document.getElementById()</tt> function
- of the DOM. Like the DOM function, this one returns the element that has the id passed as an argument.
-</p>
-
-<p id="830730" class="block-content">
- Unlike the DOM function, though, this one goes further. You can pass more than one id and
- <tt>$()</tt> will return an <tt>Array</tt> object with
- all the requested elements. The example below should illustrate this.

-
-<h2 id="6704">Getting the coordinates of the mouse pointer</h2>
-
-<p id="840742" class="block-content">Drag and drop, dynamic element resizing, games, and

-the mouse. Prototype makes this fairly simple. The code below tracks

-an input box named mouse.</p>

-</com:TTextHighlighter>
-
-<p id="840743" class="block-content">If we wanted to observe the mouse location when it was

-<h2 id="6706">Events, Binding, and Objects</h2>
-
-<p id="840745" class="block-content">Everything has been fairly straight forward so far, but things
-start getting a little trickier when you need to work with events in
-and object-oriented environment. You have to deal with binding and funky
-looking syntax that might take a moment to get your head around.</p>
-
-<p id="840746" class="block-content">Lets look at some code so you can get a better understanding of what I'm talking about.</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840260">
-EventDispenser = Class.create();

-<p id="840747" class="block-content">Whoa! What's going on here? Well, we've defined our a
-custom class <tt>EventDispenser</tt>. We're going to be using this class
-to setup events for our document. Most of this code is a
-rewrite of the code we looked at earlier except this time, we
-are working from inside an object.</p>
-
-<p id="840748" class="block-content">Looking at the <tt>initialize</tt> method, we can really see how
-things are different now. Take a look at the code below:</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840261">
-// Observe clicks on our list items
-$$(this.list + " li").each(function(item)
-{
- Event.observe(item, 'click', this.showTagName.bindEvent(this));
-}.bind(this));
-</com:TTextHighlighter>
-
-<p id="840749" class="block-content">We've got iterators, binding and all sorts of stuff going on.
-Lets break down what this chunk of code is doing.</p>
-
-<p id="840750" class="block-content">First we are hunting for a collection of elements based on
-it's CSS selector. This uses the Prototype selector function <tt>$$()</tt>.
-After we've found the list items we are dealing with we send
-those into an each iteration where we will add our observers.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840262">
-Event.observe(item, 'click', this.showTagName.bindEvent(this));
-</com:TTextHighlighter>
-
-<p id="840751" class="block-content">Now looking at the code above, you'll notice the <tt>bindEvent</tt> function.
-This takes the method before it <tt>showTagName</tt> and treats it as the
-method that will be triggered when, in this case,
-someone clicks one of our list items.</p>
-
-<p id="840752" class="block-content">You'll also notice we pass this as an argument to the <tt>bindEvent</tt> function.
-This simply allows us to reference the object in context <tt>EventDispenser</tt>
-inside our function <tt>showTagName(event)</tt>. If the <tt>showTagName</tt> function
-requires additional parameters, you can attach them to the later parameters of <tt>bindEvent</tt>. For example</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840263">
-this.showTagName.bindEvent(this, param1, param2);
-
-//where the showTagName function is defined as
-showTime : function (event, param1, param2) { ... }
-</com:TTextHighlighter>
-
-<p id="840753" class="block-content">Moving on, you'll see <tt>bind(this)</tt> attached to our iterator function.
-This really has nothing to do with events, it is only here to allow me to
-use <tt>this</tt> inside the iterator. If we did not use <tt>bind(this)</tt>, I could not
-reference the method <tt>showTagName</tt> inside the iterator.</p>
-
-<p id="840754" class="block-content">Ok, so we'll move on to looking at our methods that actually get
-called when an event occurs. Since we've been dealing with <tt>showTagName</tt>, lets look at it.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840264">
-showTagName: function(event)
-{
- alert(Event.element(event).tagName);
-}
-</com:TTextHighlighter>
-
-<p id="840755" class="block-content">As you can see, this function accepts one argument--the event.
-In order for us to get the element which fired the event we need to
-pass that argument to <tt>Event.element</tt>. Now we can manipulate it at will.</p>
-
-<p id="840756" class="block-content">This covers the most confusing parts of our code. The text above is also
-relevant to the remaining parts of our code. If there is anything about
-this you don't understand, feel free to ask questions in the forum.</p>
-
-<h2 id="6707">Removing Event Listeners</h2>
-
-<p id="840757" class="block-content">This one threw me for a loop the first time I tried to use it.
-I tried something similar to what I did in the <tt>Event.observe</tt>
-call with the exception of using <tt>stopObserving</tt>, but nothing seemed
-to change. In other words, the code below does <b>NOT</b> work.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840265">
-$$(this.list + " li").each(function(item)
-{
- Event.stopObserving(item, 'click', this.showTagName);
-}.bind(this));
-</com:TTextHighlighter>
-
-<p id="840758" class="block-content">What's the deal here? The reason this does not work is because there
-is no pointer to the observer. This means that when we passed <tt>this.showTagName</tt>
-in the <tt>Event.observe</tt> method before hand, we passed it as an
-anonymous function. We can't reference an anonymous function
-because it simply does not have a pointer.</p>
-
-<p id="840759" class="block-content">So how do we get the job done? All we need to do is give the
-observing function a pointer, or the jargon free version: Set a variable
-that points to <tt>this.showTagName</tt>. Ok, lets change our code a bit.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840266">
-this.showTagObserver = this.showTagName.bindEvent(this);
-
-// Observe clicks on our list items
-$$(this.list + " li").each(function(item)
-{
- Event.observe(item, 'click', this.showTagObserver);
-}.bind(this));
-</com:TTextHighlighter>
-
-<p id="840760" class="block-content">Now we can remove the event listeners from our list like this:</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840267">
-$$(this.list + " li").each(function(item)
-{
- Event.stopObserving(item, 'click', this.showTagObserver);
-}.bind(this));

-<p id="840747" class="block-content">Whoa! What's going on here? Well, we've defined our a
-custom class <tt>EventDispenser</tt>. We're going to be using this class
-to setup events for our document. Most of this code is a
-rewrite of the code we looked at earlier except this time, we
-are working from inside an object.</p>
-
-<p id="840748" class="block-content">Looking at the <tt>initialize</tt> method, we can really see how
-things are different now. Take a look at the code below:</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840261">
-// Observe clicks on our list items
-$$(this.list + " li").each(function(item)
-{
- Event.observe(item, 'click', this.showTagName.bindEvent(this));
-}.bind(this));
-</com:TTextHighlighter>
-
-<p id="840749" class="block-content">We've got iterators, binding and all sorts of stuff going on.
-Lets break down what this chunk of code is doing.</p>
-
-<p id="840750" class="block-content">First we are hunting for a collection of elements based on
-it's CSS selector. This uses the Prototype selector function <tt>$$()</tt>.
-After we've found the list items we are dealing with we send
-those into an each iteration where we will add our observers.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840262">
-Event.observe(item, 'click', this.showTagName.bindEvent(this));
-</com:TTextHighlighter>
-
-<p id="840751" class="block-content">Now looking at the code above, you'll notice the <tt>bindEvent</tt> function.
-This takes the method before it <tt>showTagName</tt> and treats it as the
-method that will be triggered when, in this case,
-someone clicks one of our list items.</p>
-
-<p id="840752" class="block-content">You'll also notice we pass this as an argument to the <tt>bindEvent</tt> function.
-This simply allows us to reference the object in context <tt>EventDispenser</tt>
-inside our function <tt>showTagName(event)</tt>. If the <tt>showTagName</tt> function
-requires additional parameters, you can attach them to the later parameters of <tt>bindEvent</tt>. For example</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840263">
-this.showTagName.bindEvent(this, param1, param2);
-
-//where the showTagName function is defined as
-showTime : function (event, param1, param2) { ... }
-</com:TTextHighlighter>
-
-<p id="840753" class="block-content">Moving on, you'll see <tt>bind(this)</tt> attached to our iterator function.
-This really has nothing to do with events, it is only here to allow me to
-use <tt>this</tt> inside the iterator. If we did not use <tt>bind(this)</tt>, I could not
-reference the method <tt>showTagName</tt> inside the iterator.</p>
-
-<p id="840754" class="block-content">Ok, so we'll move on to looking at our methods that actually get
-called when an event occurs. Since we've been dealing with <tt>showTagName</tt>, lets look at it.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840264">
-showTagName: function(event)
-{
- alert(Event.element(event).tagName);
-}
-</com:TTextHighlighter>
-
-<p id="840755" class="block-content">As you can see, this function accepts one argument--the event.
-In order for us to get the element which fired the event we need to
-pass that argument to <tt>Event.element</tt>. Now we can manipulate it at will.</p>
-
-<p id="840756" class="block-content">This covers the most confusing parts of our code. The text above is also
-relevant to the remaining parts of our code. If there is anything about
-this you don't understand, feel free to ask questions in the forum.</p>
-
-<h2 id="6707">Removing Event Listeners</h2>
-
-<p id="840757" class="block-content">This one threw me for a loop the first time I tried to use it.
-I tried something similar to what I did in the <tt>Event.observe</tt>
-call with the exception of using <tt>stopObserving</tt>, but nothing seemed
-to change. In other words, the code below does <b>NOT</b> work.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840265">
-$$(this.list + " li").each(function(item)
-{
- Event.stopObserving(item, 'click', this.showTagName);
-}.bind(this));
-</com:TTextHighlighter>
-
-<p id="840758" class="block-content">What's the deal here? The reason this does not work is because there
-is no pointer to the observer. This means that when we passed <tt>this.showTagName</tt>
-in the <tt>Event.observe</tt> method before hand, we passed it as an
-anonymous function. We can't reference an anonymous function
-because it simply does not have a pointer.</p>
-
-<p id="840759" class="block-content">So how do we get the job done? All we need to do is give the
-observing function a pointer, or the jargon free version: Set a variable
-that points to <tt>this.showTagName</tt>. Ok, lets change our code a bit.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840266">
-this.showTagObserver = this.showTagName.bindEvent(this);
-
-// Observe clicks on our list items
-$$(this.list + " li").each(function(item)
-{
- Event.observe(item, 'click', this.showTagObserver);
-}.bind(this));
-</com:TTextHighlighter>
-
-<p id="840760" class="block-content">Now we can remove the event listeners from our list like this:</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840267">
-$$(this.list + " li").each(function(item)
-{

-Bimbingan ini didasarkan pada <a href="http://www.sergiopereira.com/articles/prototype.js.html">
-Catatan Pengembang untuk prototype.js</a> oleh Sergio Pereira.
-
-<h2 id="6603">Apa itu?</h2>
-<p id="830726" class="block-content">
-Dalam hal Anda tidak pernah menggunakannya, <a href="http://prototype.conio.net">prototype.js</a> adalah librari
- JavaScript yang ditulis oleh <a href="http://www.conio.net">Sam Stephenson</a>.
- Pemikiran yang hebat ini dan kode <b>sesuai-standar</b> yang ditulis dengan baik mengambil banyak beban terkait dengan pembuatan halaman web sangat interaktif dan kaya yang mengkarakterkan Web 2.0 di belakang Anda.
-</p>
-
-<p id="830727" class="block-content">
- Jika Anda baru saja mencoba menggunakan librari ini, Anda mungkin mencatat bahwa dokumentasi bukanlah salah satu titik yang terkuat. Seperti banyak pengembang lain sebelum saya, saya mempelajari prototype.js dengan membaca kode sumber dan melakukan percobaan denganya. Saya pikir akan baik jika mengambil catatan selama saya mempelajari dan berbagi dengan orang lain.
-</p>
-<p id="830728" class="block-content">
- Setelah Anda membaca contoh dan referensi, para pengembang yang terbiasa dengan bahasa pemrograman Ruby akan mencatat kesamaan maksud antara kelas built-in Ruby dan banyak ekstensi diimplementasikan oleh librari ini.

-<h2 id="6604">Menggunakan fungsi <tt>$()</tt></h2>
-<p id="830729" class="block-content">
- Fungsi <tt>$()</tt> adalah jalan pintas yang siap digunakan untuk fungsi yang semua-terlalu-sering <tt>document.getElementById()</tt> terhadap DOM. Seperti fungsi DOM, fungsi ini mengembalikan elemen yang id-nya dikirimkan sebagai sebuah argumen.
-</p>
-
-<p id="830730" class="block-content">
- Tidak seperti fungsi DOM, bagaimanapun juga, yang satu ini melampauinya. Anda dapat mengirimkan lebih dari satu id dan
- <tt>$()</tt> akan mengembalikan obyek <tt>Array</tt> dengan semua elemen yang diminta. Contoh di bawah seharunya menggambarkan ini.
-</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_830252">
-<com:TClientScript UsingClientScripts="prado" />
-<div id="myDiv">
- <p id="830731" class="block-content">This is a paragraph</p>
-</div>
-
-<div id="myOtherDiv">

- }
-}
-/*]]>*/
-</script>
-</com:TTextHighlighter>
-<p id="830733" class="block-content">
- Hal baik lainnya dari fungsi ini adalah bahwa Anda bisa mengirimkan baik string <tt>id</tt> ataupun elemen obyek itu sendiri, yang menjadikan fungsi ini sangat berguna ketika membuat fungsi lain yang juga mengambil bentuk argumen.

-
-<h2 id="6605">Menggunakan fungsi <tt>$F()</tt></h2>
-
-<p id="830734" class="block-content">

-
-<p id="840748" class="block-content">Melihat metode <tt>initialize</tt>, sebenarnya kita dapat melihat bagaimana sesuatu menjadi berbeda sekarang. Lihat kode di bawah ini:</p>

-
-<p id="840749" class="block-content">Kita mendapatkan iterator, penyatuan dan semua hal lainnya. Mari kita rinci apa yang dikerjakan kode ini.</p>
-
-<p id="840750" class="block-content">Pertama kita memburu koleksi elemen berdasarkan selektor CSS. Ini menggunakan fungsi selektor Prototipe <tt>$$()</tt>.
-Setelah kita menemukan daftar item kita berhadapan dengan apa yang kita kirim ke dalam setiap iterasi di mana kita akan menambahkan pengamat kita.</p>

-Event.observe(item, 'click', this.showTagName.bindEvent(this));
-</com:TTextHighlighter>
-
-<p id="840751" class="block-content">Sekarang, melihat kode di atas, Anda akan mencatat fungsi <tt>bindEvent</tt>. Ini mengambil metode sebelumnya <tt>showTagName</tt> dan memperlakukannya sebagai metode yang akan dipicu ketika seseorang mengklik salah satu dari item daftar kita.</p>
-
-<p id="840752" class="block-content">Anda juga akan mencatat bahwa kita mengirimkan ini sebagai argumen ke fungsi <tt>bindEvent</tt>.
-Ini membolehkan kita untuk mereferensi obyek dalam konteks <tt>EventDispenser</tt>
-di dalam fungsi <tt>showTagName(event)</tt> kita. Jika fungsi <tt>showTagName</tt> memerlukan parameter tambahan, Anda melampirkannya ke parameter terakhir dari <tt>bindEvent</tt>. Sebagai contoh</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840263">
-this.showTagName.bindEvent(this, param1, param2);
-
-//di mana fungsi showTagName didefinisikan seperti
-showTime : function (event, param1, param2) { ... }
-</com:TTextHighlighter>
-
-<p id="840753" class="block-content">Selanjutnya, Anda akan melihat <tt>bind(this)</tt> yang dilampirkan ke fungsi iterator.
-Ini sama sekali tidak berkaitan dengan event, ia berada di sini untuk membolehkan saya menggunakan <tt>this</tt> di dalam iterator. Jika kita tidak menggunakan <tt>bind(this)</tt>, saya tidak bisa mereferensi metode <tt>showTagName</tt> di dalam iterator.</p>
-
-<p id="840754" class="block-content">Ok, kita berlanjut untuk melihat metode kita yang sebenarnya dipanggil saat terjadi event. Karena kita sudah berhadapan dengan <tt>showTagName</tt>, mari kita lihat itu.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840264">
-showTagName: function(event)
-{
- alert(Event.element(event).tagName);
-}
-</com:TTextHighlighter>
-
-<p id="840755" class="block-content">Seperti yang Anda lihat, fungsi ini menerima satu argumen--event.
-Agar kita mendapatkan elemen yang memicu event kita perlu mengirimkan argumen ke <tt>Event.element</tt>. Sekarang kita dapat memanipulasinya kapan saja.</p>
-
-<p id="840756" class="block-content">Ini mencakup bagian yang paling membingungkan dari kode kita. Teks di atas juga relevan untuk bagian sisa dari kode kita. Jika ada sesuatu mengenai ini yang tidak Anda mengerti, jangan ragu-ragu untuk mengajukan pertanyaan dalam forum.</p>
-
-<h2 id="6707">Menghapus Pendengar Event</h2>
-
-<p id="840757" class="block-content">Yang satu ini melontarkan saya dari lingkaran untuk pertama kali saya mencoba menggunakannya.
-Saya mencoba sesuatu yang mirip dengan apa yang saya lakukan dalam pemanggilan <tt>Event.observe</tt> dengan kekecualian penggunaan <tt>stopObserving</tt>, tapi tidak ada yang berubah. Dengan kata lain, kode di bawah ini <b>TIDAK</b> bekerja.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840265">
-$$(this.list + " li").each(function(item)
-{
- Event.stopObserving(item, 'click', this.showTagName);
-}.bind(this));
-</com:TTextHighlighter>
-
-<p id="840758" class="block-content">Apa yang terjadi di sini? Alasan ini tidak bekerja karena tidak ada penunjuk ke pengamat. Ini berarti bahwa ketika kita mengirimkan <tt>this.showTagName</tt> dalam metode <tt>Event.observe</tt> sebelumnya, kita mengirimkannya sebagai fungsi anonim. Kita tidak bisa mereferensi fungsi anonim karena ia tidak mempunyai penunjuk.</p>
-
-<p id="840759" class="block-content">Lalu bagaimana kita yakin pekerjaan diselesaikan? Semua yang kita perlukan adalah memberikan fungsi mengamati penunjuk, atau kelompok versi bebas: Setel variabel yang mengarah ke <tt>this.showTagName</tt>. Ok, mari kita ubah kode kita sedikit.</p>
-
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840266">
-this.showTagObserver = this.showTagName.bindEvent(this);
-
-// Amati klik pada item list kita
-$$(this.list + " li").each(function(item)
-{
- Event.observe(item, 'click', this.showTagObserver);
-}.bind(this));
-</com:TTextHighlighter>
-
-<p id="840760" class="block-content">Sekarang kita bisa menghapus pendengar event dari daftar kita seperti ini:</p>
-<com:TTextHighlighter Language="javascript" CssClass="source block-content" id="code_840267">
-$$(this.list + " li").each(function(item)
-{
- Event.stopObserving(item, 'click', this.showTagObserver);
-}.bind(this));
